Box 45Multiple publishers

• If more than one publisher is found in a document, use the first one given or the one set in the largest type or bold type
• An alternative is to use the publisher likely to be most familiar to the audience of the reference list. For example, use an American publisher for a US audience and a London publisher for a British one.
• Do not list multiple publishers. For those publications with joint or co-publishers, use the name given first as the publisher and include the name of the second as a note if desired. For example, use "Jointly published by the Canadian Pharmacists Association".
• End publisher information with a semicolon
